Application filed March 20, 1909. Serial No. @84313.

To all whom 'it may concern:

Be it known that I, CHARLES MILLER, a citizen of the United States, andresident of Syracuse, in the county of Onondaga, in the State of NewYork, have invented new and useful Improvements in Socket-Wrenches, ofwhich the following, taken in connection with the accompanying drawings,is a full,

clear, and exact description.

This invention relates to the class of socket-wrenches embodying aholder adapted to receive a stem provided with a socket designed to beapplied to a nut or other similar shaped object required to be turned,said stem being detachable so as to permit the use of stems havingdifl'erent sized sockets, and the holder having a handle or barconnected to it for turning the same.

One of the objects of the present invention is to provide a wrench ofthe aforesaid character which will permit the handle to be set atdiflerent angles in relation to the holder in order that the handle mayclear obstacles which might otherwise tend to interfere with itsoperation in some instances.

Another object of the invention is to produce a wrench. havinginterchangeable parts whereby its etiiciency will be increased.

Other objects of the invention will be apparent from the novelarrangement and combination of the component parts of the socket-Wrenchhereinafter fully described and set forth in the claims.

In the accompanying drawings Figure 1 is a plan view of thesocket-wrench constructed in accordance with my invention; Fig. 2 is aside view showing by dotted lines the adaptability of the handle to beswung to various positions; Fig. 3 shows the side of the wrench viewedreverse to Fig. 2; Fig. 4 is a longitudinal section on the line w-ac inFig. 2; Fig. 5 is a transverse section on the line v -y in Fig. 2; Fig.(3 is a transverse section on the line -zz in Fig. 4; Fig. 7 is a sideview of the wrench showing parts interchanged; Fig. 8 is a detached sideview of the operating handle or bar; and Fig. 9 is a detached side viewof the stem which is formed with the nutsocket.

Like characters of reference indicate like parts in the several views ofthe drawings.

My improved wrench comprises a holder -1-- which consists of acast-metal sleeve preferably formed square in cross-section and adaptedto receive a removable stem 2 formed with the well known socket -3-designed to be applied to a nut or snnilar shaped object required to beturned. This stem may be retained in the holder 1- by any suitablemeans, but preferably by an elongated spring-plate 4- secured in alongitudinal channel -5 provided in the holder, said plate beingdesigned to secure the stem by frictional engagement therewith.

This wrench also comprises a handle which essentially has a pivotalconnection with the holder 1. low and is formed square in cross-sectionand may be composed of steel or any other metal and is provided on itsattaching end with a cast-metal sleeve 7 of corresponding shape in crosssection. said handle being held detachably in the sleeve by frictionalengagement with a spring-plate -8 suitably secured in a longitudinalchannel 9-- within the sleeve as shown in Figs. 2 and 6. This sleeve isformed with a socket -10 which receives a ball 1l' formed integral withthe holder or sleeve -1. Said ball is hollow and is provided withoppositely disposed openings -1'219.- which are slightly elongated andcoincide with circular apertures -13-13-- provided at opposite sides ofthe sockct 1(), through which openings and apertures passes a pivot pinl-l-- whereby the aforesaid handle may be swung into various angles inrelation to the holder -1. This pin is preferably of the form of ascrew, therefore one of the apertures 13 is correspondingly threaded andthe other aperture provided with a countersink for the reception of thescrew-head as clearly illustrated in Fig. 4-. The aforesaid-apertures--12 l2 are elongated for the purpose of allowing the ball -11- to bedrawn into frictional contact with the socket 10 so as to retain thehandle in the desired position. To efl ect this result I provide a bolt-15 which passes through a central opening -l6 in the socket, and througha coinciding slot l7 in the ball, said bolt being formed with ascrew-head 18 seated in a countersink of the opening. A nut 19 on theprotruding end of the bolt is formed with a convex inner face to conformto the inner surface of the ball. It is obvious that by tightening thesaid nut the Said handle is hol ball will be firmly drawn into thesocket for the purpose stated. The aforesaid slot 17-- in the ballaccommodates the bolt to permit the said ball to turn in its socketincident to theswinging of the handle as indicated. It will be observedthat by. providing the two members -1-7- of the same. internaldimensions, the stem -2 and handle (3- may be interchangeably appliedthereto as shown in Fig. 7. This interchangeability of parts permitsmore extended use of the wrench.

I refer to provide the free end of the hand e 6- with a permanentlyattached sleeve 18 having a friction-plate -l9 secured in an internallongitudinal channel --20 in said sleeve as shown in Figs. 2 and 4. Byproviding this sleeve l8 an additional section may be applied to thehandle if required.

hat I claim as my invention is 1. A wrench of the class specifiedcomprising a holder having a detachable nutsocket member, and anoperating handle piv otally and detachably connected to said holder,said nut-socket member and handle being interchangeable in theirattachments as set forth.

2. A wrench of the class specified comprising a holder provided with adetachable nut-socket member and formed with a hollow slotted ball, anoperating handle proball, whereby the shaped to conform to the interiorof the ball for the purpose set forth.

3. A wrench of the class specified com prising a holder consisting of asleeve for a nut-socket member, and formed with a hollow slotted ball, ahandle provided on one end with a detachable sleeve formed with a socketreceiving said ball, and means passing through the socket and into theball for retaining said ball and socket in frictional connection as setforth.

4. A socket-wrench comprising a holder, a nut-socket member securedremovably in the holder, a handle, a pivotal coupling for the handle andholder, said handle being detachable, and the nut-socket member andhandle interchangeable in their connections as set forth and shown.

5. A socket-wrench comprising a holder formed with a hollow ballprovided with oppositely disposed apertures, a nut-socket member formedwith a stem secured detachably in said holder, a handle provided with asocket having apertures coinciding with the apertures of the ball, apivot-pin fitted to the apertures of the socket and passing looselythrough the apertures of the handle is permitted to swing to differentangles in relation to the aforesaid holder, and means for drawing .saidball and its socket into frictional contact to sustain the handle in therequired position as set forth.
